        <h3 id="访问慢的原因"><a href="#访问慢的原因" class="headerlink" title="访问慢的原因"></a>访问慢的原因</h3><p>DNS解析耗时。</p>
<ul>
<li>DNS（域名系统，Domain Name System）：将<a target="_blank" rel="noopener" href="https://baike.baidu.com/item/%E5%9F%9F%E5%90%8D">域名</a>和<a target="_blank" rel="noopener" href="https://baike.baidu.com/item/IP%E5%9C%B0%E5%9D%80">IP地址</a>相互映射的一个分布式数据库。</li>
<li>DNS（域名服务器，Domain Name Server）：将域名转换为IP地址的服务器。</li>
</ul>
<h3 id="解决方案"><a href="#解决方案" class="headerlink" title="解决方案"></a>解决方案</h3><p>手动修改系统hosts文件，将github域名对应的ip保存到hosts文件中，访问github的时候可以直接访问该ip，不需要dns解析。</p>
<ul>
<li>windows系统在<code>C:\Windows\System32\drivers\etc\hosts</code>，打开普通用户读写权限<code>右键-属性-安全-选择当前用户-编辑-修改权限-确认</code></li>
<li>mac系统在<code>/etc/hosts</code>，sudo申请权限</li>
</ul>
<blockquote>
<p>Hosts是一个没有扩展名的系统文件，其作用就是保存常用的网址域名与其对应IP地址的映射，当用户在浏览器中输入一个需要登录的网址域名时，系统会首先自动从Hosts文件中寻找对应的IP地址，一旦找到，系统会立即打开对应网页，如果没有找到，则系统会将网址提交DNS服务器进行IP地址的解析，再进行访问。</p>
</blockquote>
<p>步骤如下：</p>
<ol>
<li><p><a target="_blank" rel="noopener" href="https://github.com.ipaddress.com/">查询github网站IP</a></p>
</li>
<li><p><a target="_blank" rel="noopener" href="https://fastly.net.ipaddress.com/github.global.ssl.fastly.net">查询github域名IP</a></p>
</li>
<li><p><a target="_blank" rel="noopener" href="https://github.com.ipaddress.com/assets-cdn.github.com">查询github静态资源IP</a></p>
</li>
<li><p>修改hosts文件，添加如下映射。前三个步骤如果查到多个IP的话可以配置多个</p>
<figure class="highlight text"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br></pre></td><td class="code"><pre><span class="line">140.82.113.4 github.com</span><br><span class="line">199.232.69.194 github.global.ssl.fastly.net</span><br><span class="line">185.199.108.153 assets-cdn.github.com</span><br><span class="line">185.199.109.153 assets-cdn.github.com</span><br><span class="line">185.199.110.153 assets-cdn.github.com</span><br><span class="line">185.199.111.153 assets-cdn.github.com</span><br></pre></td></tr></table></figure></li>
<li><p>cmd执行命令，刷新DNS缓存：<code>ipconfig /flushdns</code></p>
</li>
<li><p>隔一段时间ip可能会变，需要重新配置</p>
</li>
<li><p>Github上有牛人提供了脚本，一键获取github最新的IP，并更新hosts文件，clone下来，执行index.cmd即可。<a target="_blank" rel="noopener" href="https://github.com/luozheao/setHost">https://github.com/luozheao/setHost</a></p>
</li>
</ol>
<p>附：查询ip地址的网站：<a target="_blank" rel="noopener" href="https://www.ipaddress.com/">ipaddress网站</a>、<a target="_blank" rel="noopener" href="http://tool.chinaz.com/dns">站长工具</a></p>
<h3 id="GitPage博客无法访问"><a href="#GitPage博客无法访问" class="headerlink" title="GitPage博客无法访问"></a>GitPage博客无法访问</h3><p>同理，只需要查询博客地址对应的IP，配置hosts就可以解决了。</p>
<p>困扰已久的问题，一直以为是需要翻墙vpn，原来是DNS服务器限制。</p>
